At least one example embodiment relates to a container for separately containing pre-vapor formulation ingredients prior to filling a reservoir of an electronic vaping device.

FIG. 1 is a side, cross-sectional view of a refill vial including a first compartment and a second compartment according to an example embodiment.

In at least one example embodiment, as shown in FIG. 1, a container 10 for separately containing pre-vapor formulation ingredients includes a body 15. The body 15 has an opening 25 therein. The body may also include a first compartment 35 and a second compartment 40 therein. A first seal 30 is positioned between the first compartment 35 and the second compartment 40. The container 10 also includes a lid 20 configured to cover and/or seal the opening 25 of the container 10.

In at least one example embodiment, the first compartment 35 may be the same size and/or volume as the second compartment 40. In at least one example embodiment, at least one of the first compartment 35 and the second compartment 40 has a volume ranging from about 1 milliliter (mL) to about 200 mL. In at least one example embodiment, the first compartment 35 has a larger or smaller size and/or volume than the second compartment 40.

In at least one example embodiment, the first compartment 35 and the second compartment 40 each contains some ingredients of a pre-vapor formulation.

The pre-vapor formulation is a material or combination of materials that may be transformed into a vapor. For example, the pre-vapor formulation and/or the pre-vapor formulation ingredients may be in the form of a liquid, a solid and/or a gel. The pre-vapor formulation ingredients include, but are not limited to, water, beads, solvents, active ingredients, ethanol, plant extracts, natural or artificial flavors, nicotine, vapor formers such as glycerin and propylene glycol, water, and/or acids.

In at least one example embodiment, the first compartment 35 may contain different pre-vapor formulation ingredients from the second compartment 40. Thus, nicotine may be contained in the first compartment 35 and the vapor formers may be contained in the second compartment 40 to prevent and/or minimize chemical reactions prior to refilling a reservoir of an electronic vaping device. In addition, maintaining ingredients in separate compartments may increase shelf-life by at least about 1 week (e.g., at least 2 weeks, at least one month, at least three months, at least six months, at least nine months, or at least one year).

For example, in at least one example embodiment, flavors may be contained in the first compartment 35 and vapor formers may be contained in the second compartment 40. Some flavors may be unstable in vapor formers, such as propylene glycol. Thus, separately storing these ingredients increases stability and/or shelf-life.

For example, in at least one example embodiment, acids may be contained in the first compartment 35 and vapor formers may be contained in the second compartment 40 to avoid and/or minimize reactions between the flavors and vapor formers.

In another example embodiment, the first compartment 35 may contain ingredients in powder form, while the second compartment 40 contains ingredients in liquid and/or gel form.

In at least one example embodiment, the first seal 30 is a frangible seal 30 that may be broken to expose ingredients in the first compartment 35 to ingredients in the second compartment 40. The first seal 30 is substantially impermeable, such that the ingredients contained in the first compartment 35 and/or the second compartment 40 cannot pass through the first seal 30.

In at least one example embodiment, as shown in FIG. 1, the lid 20 is connected to the first seal 30, such that when the lid 20 is removed, the first seal 30 is broken and the ingredients in the first compartment 35 are mixed with ingredients in the second compartment 40.

In at least one example embodiment, the lid 20 is a screw-top lid. In some example embodiments, the lid 20 may be a child-resistant lid. In other example embodiments, the lid 20 may have a snap-fit (or other type) connection about the opening 25 of the container 10.

In at least one example embodiment, the first seal 30 is formed of at least one of a plastic and a metal foil coated with an inert substance. In at least one example embodiment, the container 10 and the first seal 30 are formed of the same material. In other example embodiments, the container 10 and the first seal 30 are formed of different materials. The first seal 30 is about 50 microns to about 1000 microns thick. In at least one example embodiment, the first seal 30 is thick enough to withstand pressure applied during shipment and storage, but thin enough to easily break when the lid 20 is removed from the container 10 or action is taken to break the seal as described in FIG. 6 described below. In at least one example embodiment, the structure in FIG. 1 may be made out of an insert plastic material, such as polyethylene terephthalate or polystyrene using extrusion molding, blow molding, or thermoforming techniques. The individual compartments may be made in a single process step or the compartments may be formed in separate steps and brought together to create the structure of FIG. 1.

In at least one example embodiment, the body 15, the lid 20, and/or the seal 30 may be coated with an inert substance so as to prevent and/or minimize reactions between the ingredients of the pre-vapor formulation with the materials that form the body 15, the lid 20, and/or the seal 30. The inert substance may be a plastic coating. For example, the seal 30 may be formed of a metal foil coated with a plastic or another inert substance.

In at least one example embodiment, as shown in FIG. 1, the seal 30 is positioned substantially vertically between the first compartment 35 and the second compartment 40.

FIG. 2 is a side, cross-sectional view of a refill vial including a first compartment, a second compartment, and a third compartment according to an example embodiment.

In at least one example embodiment, as shown in FIG. 2, the container 10 is substantially the same as the container of FIG. 1, but the container 10 also includes a third compartment 45 in the container body 15. The third compartment 45 contains at least a third ingredient, which may be the same or different than ingredients contained in the first compartment 35 and the second compartment 40.

In at least one example embodiment, a second seal 43 separates the third compartment 45 from at least one of the first compartment 35 and the second compartment 40. The second seal 43 is frangible and substantially impermeable, and may be formed of the same or a different material than the first seal 30. The second seal 43 may also include an inert coating thereon.

In at least one example embodiment, the second seal 43 is positioned substantially vertically within the body 15 of the container 10. In other example embodiments, the second seal 43 may be horizontally positioned while the first seal 30 is vertically positioned (not shown).

In at least one example embodiment, the second seal 43 is connected to one or more of the lid 20 and the first seal 30.

FIG. 3 is a side, cross-sectional view of a refill vial including a substantially horizontally extending seal separating a first compartment and a second compartment according to an example embodiment.

In at least one example embodiment, as shown in FIG. 3, the container 10 is substantially the same as the container of FIG. 1, but the first seal 30 extends substantially horizontally between the first compartment 35 and the second compartment 40. In addition, a seal connector 50 may extend between the lid 20 and the first seal 30 so as to connect the lid 20 to the first seal 30. Thus, when the lid 20 is removed, the seal connector 50 pulls the first seal 30 so as to break the first seal 30.

At least one example embodiment relates to a container for separately containing pre-vapor formulation ingredients prior to filling a reservoir of an electronic vaping device.

FIG. 4 is a side, cross-sectional view of a refill vial including a first compartment and a dropper according to an example embodiment.

In at least one example embodiment, as shown in FIG. 4, a container 10 includes a container body 15 having an opening 25 therein, a first compartment 35 in the container body 15, a lid 20 covering the opening 25, and a dropper 55 extending from the lid 20 into the first compartment 35. The first compartment 35 contains at least a first ingredient. The dropper 55 contains at least a second ingredient. The dropper 55 including a dropper opening 70. The dropper opening 70 is covered with a covering 60. The covering 60 is removable and substantially impermeable.

In at least one example embodiment, the dropper 55 includes measurement markings 65 on a side thereof. The measurement markings 65 include indicia indicating amounts of the second ingredient contained in the dropper 55. The measurement markings 65 may indicate amounts in mL or in other measurements. Once the dropper 55 is removed, a desired amount of the ingredient contained in the dropper 55 can be ejected from the dropper 55 into the ingredients contained in the first compartment 35. Thus, the pre-vapor formulation may be tailored to contain a desired amount of nicotine, acids, and/or flavors.

In at least one example embodiment, the covering 60 is formed of at least one of a plastic and a metal foil coated with an inert substance. The covering 60 may extend over the dropper opening 70 and along sides of the dropper 55. The covering 60 may include a tear strip or other gripping portion (not shown), which can be grasped to remove the covering 60.

FIG. 5 is a side, cross-sectional view of a refill vial including a first compartment, a second compartment, and a dropper according to an example embodiment.

In at least one example embodiment, as shown in FIG. 5, the container 10 is generally the same as in FIG. 4, except that the container 10 includes a second compartment 40. The second compartment 40 contains at least a third ingredient. The container 10 may also include a first seal 30 between the first compartment 35 and the second compartment 40. The first seal 30 is frangible and substantially impermeable. The first seal 30 may be connected to at least one of the lid 20 and the dropper 55, such that the first seal 30 is broken when the lid 20 and/or the dropper 55 is removed from the container 10. Thus, ingredients separately contained in the first compartment 35, second compartment 40, and/or the dropper 55 may be mixed upon opening of the container.

FIG. 6 is an illustration of a seal between a first compartment and a second compartment being broken according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 6, the seal may extend vertically through the container to form the first compartment 35 and the second compartment 40. The perforated lines indicate weak points in the seal that may be formed by altering a thickness of the seal at selected points for ease of breaking the seal.

In at least one example embodiment, if a lid is rotated as shown, the seal would break and contents of the first compartment 35 and the second compartment 40 may mix. The lid could be reapplied once the seal is broken so that the container could be shaken to induce further mixing.

FIG. 7 is a side, cross-sectional view of a refill vial including a first compartment and a second compartment according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 7, the seal 30 may form a bottom of the first compartment 35 and separate the first compartment 35 from the second compartment 40. In this example embodiment, the second compartment 40 may be filled first, then the seal 30 may be inserted over the second compartment 40, and the first compartment may then be filled. A seal connector 50 may be connected to the seal 30 to enable breaking of the seal 30 once the container is opened.
